 Adding the parameter `exclude_visibilities` to the timeline queries will exclude the statuses with the given visibilities. The parameter accepts an array of visibility types (`public`, `unlisted`, `private`, `direct`), e.g., `exclude_visibilities[]=direct&exclude_visibilities[]=private`.

 Adding the parameter `reply_visibility` to the public and home timelines queries will filter replies. Possible values: without parameter (default) shows all replies, `following` - replies directed to you or users you follow, `self` - replies directed to you.

 Pleroma is generally compatible with the Mastodon 2.7.2 API, but some newer features and non-essential features are omitted. These features usually return an HTTP 200 status code, but with an empty response. While they may be added in the future, they are considered low priority.

+# Configuring Ejabberd (XMPP Server) to use Pleroma for authentication
+
+If you want to give your Pleroma users an XMPP (chat) account, you can configure [Ejabberd](https://github.com/processone/ejabberd) to use your Pleroma server for user authentication, automatically giving every local user an XMPP account.
+
+In general, you just have to follow the configuration described at [https://docs.ejabberd.im/admin/configuration/authentication/#external-script](https://docs.ejabberd.im/admin/configuration/authentication/#external-script). Please read this section carefully. 
+
+Copy the script below to suitable path on your system and set owner and permissions. Also do not forget adjusting `PLEROMA_HOST` and `PLEROMA_PORT`, if necessary.
+
+```bash
+cp pleroma_ejabberd_auth.py /etc/ejabberd/pleroma_ejabberd_auth.py
+chown ejabberd /etc/ejabberd/pleroma_ejabberd_auth.py
+chmod 700 /etc/ejabberd/pleroma_ejabberd_auth.py
+```
+
+Set external auth params in ejabberd.yaml file:
+
+```bash
+auth_method: [external]
+extauth_program: "python3 /etc/ejabberd/pleroma_ejabberd_auth.py"
+extauth_instances: 3
+auth_use_cache: false
+```
+
+Restart / reload your ejabberd service.
+
+After restarting your Ejabberd server, your users should now be able to connect with their Pleroma credentials.
